Enhancing digestion and gut fermentation in pigs: evaluation of the effects of reconstituted and ensiled sorghum grains.

The effect of ensiling sorghum grains harvested at different dates on pig nutrient digestibility and fermentability was evaluated using approaches. A sorghum crop was divided following a randomised complete block design and distributed in 3 treatments: 1) grain harvested 113 d after sowing (40% moisture) and ensiled for 180 d (high moisture, HMG), 2) grain harvested 159 d after sowing (15% moisture), rehydrated to 40% moisture and ensiled for 180 d (reconstituted, REC), and 3) sorghum grain harvested 159 d after sowing (15% moisture) and stored dry (dry, DG). Starch content was lower in ensiled grains (HMG and REC) ( = 0.

Growth stage and ensiling: impact on chemical composition, conservation quality and in situ ruminal degradability of whole-crop oat.

Background: The effects of growth stage (GS) and ensiling were assessed on whole-crop oat's (Avena sativa L. cv. Cantara) chemical composition, silage fermentation quality and in situ ruminal degradability.

Lamb Fattening Under Intensive Pasture-Based Systems: A Review.

The benefits of pasture-based systems on the fatty acid composition of sheep meat appear to be achievable despite variability in the quality of the pastures. Lambs fed high levels of temperate pastures have an excess of N-ammonia derived from protein degradation. Furthermore, animal performance is highly variable depending on the quality of the pasture at the time of grazing, and high animal performance in these systems appears to be linked to the use of high-quality pastures with high availability, and is possibly added to by the inclusion of concentrates that allow increasing energy intake and a better use of the N in the pasture.

Ruminal use of undegraded-feed soluble protein and accuracy of the estimations of the nutrient content in ruminal bacteria.

Background: The possible escape from the rumen of undegraded-feed soluble proteins (SP) was investigated using nitrogen-15 ( N) infusions (25 mg) in three rumen and duodenum cannulated wethers. Animals were fed three isoproteic diets differing in SP content and including protein concentrates either untreated (control) or treated with solutions of either malic acid (MHT) or orthophosphoric acid (OHT) and heat.

Results: Compared with control, MHT and OHT diets reduced ruminal concentrations of ammonia-nitrogen (NH -N) by 35.

Association of residual feed intake with abundance of ruminal bacteria and biopolymer hydrolyzing enzyme activities during the peripartal period and early lactation in Holstein dairy cows.

Background: Residual feed intake (RFI) in dairy cattle typically calculated at peak lactation is a measure of feed efficiency independent of milk production level. The objective of this study was to evaluate differences in ruminal bacteria, biopolymer hydrolyzing enzyme activities, and overall performance between the most- and the least-efficient dairy cows during the peripartal period. Twenty multiparous Holstein dairy cows with daily ad libitum access to a total mixed ration from d - 10 to d 60 relative to the calving date were used.

Planning low-carbon electricity systems under uncertainty considering operational flexibility and smart grid technologies.

Electricity grid operators and planners need to deal with both the rapidly increasing integration of renewables and an unprecedented level of uncertainty that originates from unknown generation outputs, changing commercial and regulatory frameworks aimed to foster low-carbon technologies, the evolving availability of market information on feasibility and costs of various technologies, etc. In this context, there is a significant risk of locking-in to inefficient investment planning solutions determined by current deterministic engineering practices that neither capture uncertainty nor represent the actual operation of the planned infrastructure under high penetration of renewables. We therefore present an alternative optimization framework to plan electricity grids that deals with uncertain scenarios and represents increased operational details.

Effects of correcting in situ ruminal microbial colonization of feed particles on the relationship between ruminally undegraded and intestinally digested crude protein in concentrate feeds.

Background: In situ estimates of ruminally undegraded protein (RUP) and intestinally digested protein (IDP) of ten concentrates, uncorrected or corrected for the ruminal microbial colonization, were used to examine the effects of this correction on the relationship between IDP and RUP values. Both variables were established for three rumen and duodenum cannulated wethers using N labeling-techniques and considering measured rates of ruminal particle comminution (k ) and outflow (k ).

Results: A covariance analysis showed that the close relationship found between both variables (IDP = -0.

Ruminal degradation of cell wall associated nitrogenous compounds of several (15) N-labelled feeds.

Background: Ruminal in situ effective degradability (ED) of dry matter (DM), neutral (NDF) and acid (ADF) detergent fibres, total-N and NDF (NDIN) and ADF (ADIN) bound-N in sunflower seed (SS), wheat grain (WG) and wheat straw (WS) were measured in three ruminally cannulated sheep, correcting microbial N-contamination using the (15) N dilution technique modified to consider the (15) N supply to adherent bacteria.

Results: The lack of correction for N-contamination under-evaluated ED estimates in 1.52% (total-N), 28.

Protein value of cereals and cereal by-products for ruminants: a comparison between crude protein and protein-based estimates.

In situ estimates of ruminal undegraded fraction (RU) and effective intestinal digestibility (EID, corrected for microbial colonisation) of dry matter (DM), crude protein (CP) and total analysed amino acids (TAA) of rye, wheat and corn grains, wheat bran, wheat and barley distillers' dried grains with solubles (DDGS) and corn gluten feed were measured on three rumen and duodenum cannulated wethers using (15)N labelling techniques and considering ruminal rates of particle comminution (kc) and outflow. Results indicate that not considering kc and microbial colonisation led to considerable overestimations of RU which increased with feed ruminal degradation. Microbial colonisation may be also associated with overestimations of EID, whose estimates for DM, CP and TAA were predicted from parameters related with the ruminal escape of intestinally indigestible materials.

Amino acid availability in ruminants of cereals and cereal co-products.

Background: Microbial corrected in situ estimates of the ruminal undegraded fraction (RU) and intestinal effective digestibility (IED) of amino acids (AA), except tryptophan, of rye, wheat and corn grains, wheat bran, wheat and barley distilled dried grains and corn gluten feed were measured on three rumen- and duodenum-cannulated wethers using (15)N-labelling techniques and considering ruminal rates of particle comminution and outflow.

Results: The lack of microbial correction led to overestimations of the intestinal digested fraction that rose with the increase in ruminal degradability. Thus these overestimations varied widely among feeds (from 4.

Effects of the comminution rate and microbial contamination of particles in the rumen on in situ estimates of protein and amino acid digestion of expeller palm kernel and rapeseed meal.

Background: Microbial corrected effective in situ estimates of ruminal undegraded fraction (RU) and intestinal effective digestibility (IED) of dry matter (DM), crude protein (CP) and amino acids (AA) of expeller palm kernel (EPK) and rapeseed meal (RSM) were measured on three rumen- and duodenum-cannulated wethers using ¹⁵N labelling techniques and considering ruminal rates of comminution (k(c)) and outflow (k(p)) of particles.

Results: The lack of k(c) and microbial correction overestimated the RU of DM by 4.91% (EPK) and 9.

To demonstrate that percutaneous nephrolithotomy (PCNL) in the Galdakao-modified supine Valdivia position can be safely and effectively reproduced by different surgeons. A multicentre retrospective cross-sectional case study on 317 patients was conducted. The centres enrolled were four hospitals from the Spanish National Health System and provided data for consecutive PCNL from January 2008 to December 2010.

Psychological problems derived from mastectomy: a qualitative study.

Advances in treatment of breast cancer have not avoided using mastectomy in all cases, and when this happens, we are dealing with a woman who is suffering from psychological problems. In order to study this issue we have carried out a research with the collaboration of The Andalusian Association of Women with Mastectomies (AMAMA) in Seville, which provided us with a sample of 46 mastectomized women. The objective of this study is to analyze in depth the psychological reaction of women to mastectomy through its different stages from diagnosis to surgical treatment.
